Dyshidrosis, also known as dyshidrotic eczema or pompholyx, is an uncommon skin condition in which very small, fluid-filled blisters appear on the palms of your hands and the sides of your fingers. The soles of your feet also can be affected.

The blisters that occur in dyshidrosis generally last around three weeks and cause intense itching. Once the blisters of dyshidrosis dry, your skin may appear scaly. The blisters typically recur, sometimes before your skin heals completely from the previous blisters.

Treatment for dyshidrosis most often includes creams or ointments that you rub on the affected skin. In severe cases, your doctor may suggest corticosteroid pills, such as prednisone, that you take by mouth.
